Configuring EIGRP Routing Using Wildcard Masks

Configuring EIGRP Routing Using Wildcard Masks

Lab Objective:

The objective of this lab exercise is for you to learn and understand how to enable EIGRP routing using a single Autonomous System while using a wildcard mask for EIGRP network statements.

Lab Purpose:

Enabling basic EIGRP routing using wildcard masks is a fundamental skill. EIGRP is an advanced Distance Vector routing protocol. It is also a Cisco proprietary protocol that runs over IP protocol number 88. Wildcard masks allow EIGRP to be enabled for certain subnets within a major subnet and provide greater control for establish EIGRP neighbor adjacencies. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to enable basic EIGRP routing while using wildcard masks.

Certification Level:

This lab is suitable for CCNA certification exam preparation

Lab Difficulty:

This lab has a difficulty rating of 8/10

Readiness Assessment:

When you are ready for your certification exam, you should complete this lab in no more than 20 minutes

Lab Topology:

Please use the following topology to complete this lab exercise:

Task 1:

Configure the hostnames on routers R1, R2, and Sw1 as illustrated in the topology.

Task 2:

Configure VLAN 10 named EIGRP_10 and VLAN 20 named EIGRP_20 on Sw1. Next, configure Sw1 F0/2 and F0/3 as trunks. These should be connected to R1 and R2 F0/0 interfaces, respectively.

Task 3:

Configure subinterfaces Fa0/0.10 and F0/0.20 on R1 and R2. Subinterface Fa0/0.10 on either router should be associated with VLAN 10 and subinterface Fa0/0.20 on either router should be associated with VLAN 20. Configure IP addresses on both the subinterfaces as illustrated in the topology.

 Task 4:

Ping between R1 and R2 on subinterface Fa0/0.10 and Fa0/0.20 to verify IP connectivity.

Task 5:

Enable EIGRP using Autonomous System 10 between R1 and R2 F0/0.10 subinterfaces. EIGRP using Autonomous System 10 should only be enabled for these interfaces. Use a wildcard mask to achieve this.

Task 6:

EIGRP using Autonomous System 20 between R1 and R2 F0/0.20 subinterfaces. EIGRP using Autonomous System 10 should only be enabled for these interfaces. Use a wildcard mask to achieve this.

Task 7:

Verify that you have two EIGRP adjacencies on R1 and R2. One adjacency should be for EIGRP using Autonomous System 10 and the other for EIGRP using Autonomous System 20.
